Why does a weather balloon pop if it goes too high?

A.
The pressure in the balloon decreases as the temperature increases.

B.
The pressure in the balloon increases as the volume decreases.

C.
The volume of gas increases as the pressure decreases with altitude.

D.
The volume of gas increases as the amount of gas in the balloon increases.

Im guessing it is either C or D because balloons expand at high altitudes

Alright thank you so much. So it is C then

of course

But you KNOW it can't be D. The AMOUNT OF GAS INCREASES? You know the amount of gas is not increasing. Who is up there at 10,000 feet pumping more gas into the balloon. No one. There is a fixed amount of gas at the moment the balloon is released on the ground and no more is added on its way up into the great blue yonder.

Well, I'm delighted you didn't choose option A, because balloons are not into temperature drama. As for option B, I must say that balloons are not big fans of compression either. So that leaves us with options C and D. Picture this: as the balloon ascends to great heights, the air pressure decreases, causing the gas inside the balloon to expand, just like the waistline after a tasty meal. So, my friend, I would bet on option C, where the volume of gas increases as the pressure decreases with altitude. Just like my jokes, it's all about the expansion!

To determine the correct answer, let's break down the possible options:

A. The pressure in the balloon decreases as the temperature increases.
This statement is not correct in this context. As the temperature decreases with increasing altitude, the pressure also decreases.

B. The pressure in the balloon increases as the volume decreases.
This statement is also not correct. The pressure inside the balloon should decrease as the volume increases.

C. The volume of gas increases as the pressure decreases with altitude.
This statement is true. As an object, like a weather balloon, ascends to higher altitudes, the atmospheric pressure decreases. As a result, the gas inside the balloon expands, causing the volume of the balloon to increase.

D. The volume of gas increases as the amount of gas in the balloon increases.
This statement is not applicable in this situation since it does not explain why the balloon would pop at high altitudes.

Therefore, the correct answer is C. The volume of gas increases as the pressure decreases with altitude. As the pressure decreases at higher altitudes, the gas inside the balloon expands to fill the increasing volume, which can eventually lead to the balloon popping if it exceeds its structural limits.
